I'm not sure of it, a ps4 version with a keyboard (all in one) like the amiga or the c64... With a bluray writer on the right side, why not ???
I'm sure it could work... Think about it, the exclusities of the ps4 but in the same time a computer !!! I said ps4 but you can read any others names.
The big problem is which OS ??
ps:Yes, perhaps there is no demand, but i'm sure if it was done they will have buyers. ;-)
